6x-18y=-3
-2x+6y=-12
solve using either substitution or elimination

Answer 1

6x-18y=-3 -------(1)
-2x+6y=-12 ------(2)
From (2):
x = 3y + 6 --------(3)
Plug (3) into (1):
6(3y + 6) - 18y = -3
18y + 36 - 18y = -3
36 = -3 (No solution)

Answer 2

thanks

Answer 3

6x-18y=-3 -------(1)
-2x+6y=-12 ------(2)
From (2):

Plug (3) into (1):
6(3y + 6) - 18y = -3
18y + 36 - 18y = -3
36 = -3 (No solution)
